,LSAW 2 A line pipe to be manufactured or grades API 5L A (high frequency electric resistance welded) line pipe or API 5L B (submerged arc welded or electric fusion welded) pipe,API 5L X80 PSL2(L555) line pipe or API 5L X70 PSL2 pipe and API 5L X80 PSL2 (L555) pipe or API 5L X70 pipe,API 5L X70 PSL2 (L485) line pipe or API 5L X60 SCH XS (Seamless pipe)
The grade of pipe being manufactured will depend on the specific application.The most commonly used grades for high frequency electric resistance welded (HFW) line pipe include:API 5L A and API 5L X80 PSL2 (L555).Submerged arc welded (SAW) and electric fusion welded (EFW) line pipe grades include:API 5L B,API 5L X70 PSL2 (L485) and API 5L X60 SCH XS (Seamless).Each grade is designed for a specific application and can provide different levels of performance in different environments.
Advantages: The production process of submerged arc welded pipe is flexible, and any specification and wall thickness can be produced within the production range. The production efficiency is lower than that of high frequency straight seam welded steel pipe and spiral welded steel pipe. The biggest advantage of direct seam submerged arc welded pipe is that it can produce high-frequency steel pipe, spiral steel pipe, and even specifications and models that cannot be produced by seamless steel pipe. The production cost of straight seam submerged arc welded pipe is higher than that of high-frequency steel pipe and spiral steel pipe, but there are more opportunities for price discounts compared to seamless steel pipe. Scope of application: LSAW pipes are widely used in domestic heavy steel structure engineering, fluid pipeline engineering and foundation pile engineering.
